The art is really cool! The pre-rendered clay-like graphics nail that dour tone, which is further emphasized by the rusty palette. Having to strategically dash past meteors was also very fun!
The full restart on a hit was fair, it matched the shorter arcade style of gameplay, but I do think it should've gone back to the beginning of gameplay instead of booting to the menu.
I could be wrong about this, but it seems like in terms of pure score, the shrink is easily the best powerup. It makes it fairly easy to outrun meteors and reduces the time it takes to finish.
The audio is very imbalanced. The running sound and the winning music is a good deal louder than the regular music, and the hit sound effect is a LOT louder than the other sounds; it peaked my speakers to +2.0 dB!
All-in-all though, great work!
